Abstract :A kind of new remote measuring and controlling terminal system for the water supply of railway station is introduced. It can monitor the equipments of the remote station , and also can control these equipments’operation. Its hardware configuration , circuit
construction and software designing ware provided in detail. This systemwas composed of the supervision center (PC) and the remote station’sMCU system , which are lined by RS485/ Ethernet converter through Ethernet. The flexibility and expandability of the system was achieved. Its running results show that it is reliable and steady. So it is worthwhile for further practical application.
Key Words :remote measuring and controlling terminal ;water supply ;RS485 ;ethernet
